Hyunsik Choi created TAJO-983:
---------------------------------

             Summary: Worker should directly read Intermediate data stored in localhost rather than fetching
                 Key: TAJO-983
                 URL: https://issues.apache.org/jira/browse/TAJO-983
             Project: Tajo
          Issue Type: Bug
          Components: data shuffle
            Reporter: Hyunsik Choi


Currently, worker always fetches all intermediate via Fetcher and than store them in local file system even though some intermediate data already are  stored in local file system. It is inefficient and causes unnecessary I/O and extra storage occupation. We should improve it.
